I just built Bob Grove's "Flex Antenna." It works great!! The HF version
is perfect for those of us who travel. Just FYI.

That's nice. What are the design details? If I was to guess it looks
like a common mode antenna where only the center conductor is
electrically connected to the radio. At the coax far end from the radio
the center and shield are connected together. This would not be a good
antenna in an electrically noisy environment.
